Gas-liquid separation device based on chemical production

Abstract

The invention discloses a gas-liquid separation device based on chemical production, relates to the technical field of gas-liquid separators, and solves the problem that liquid separated by an existing gas-liquid separator cannot be automatically discharged after reaching a certain liquid level. The gas-liquid separation device comprises a gas-liquid separator, and the bottom of the gas-liquid separator is fixedly connected with a liquid collecting box. In the using process of the device, when water stored in the liquid collecting box reaches a certain position, liquid flows into a siphon cover through an opening and closing hole and is discharged out of the liquid collecting box through a drainage main pipe under the siphon effect, and a gas blocking mechanism can descend along with descending of the liquid level, and therefore, when the liquid level is low, the opening and closing hole is re-staggered to block the bottom of the siphon cover to prevent liquid from continuing to flow into the siphon cover, gas without gas-liquid separation in the liquid collecting box is prevented from leaking through the drainage main pipe due to excessive siphon of the liquid, the use is stable, and the automation degree is high.

Description

technical field [0001] The invention belongs to the technical field of gas-liquid separators, and more specifically relates to a gas-liquid separation device based on chemical production. Background technique [0002] The gas-liquid separator is an important equipment in the modern process industry system. It is widely used in oil hydrogenation, wet desulfurization, waste heat utilization of flue gas, wet dust removal and fermentation in the petrochemical industry to separate and remove harmful substances. substances or efficient recovery of useful substances. [0003] For example, the patent application number: CN201510419609.7 discloses a gas-liquid separation device, including: a membrane sulfonation reactor, a gas-liquid separator and a separator; the inlet of the membrane sulfonation reactor is connected to a feed line; the gas-liquid separator includes a first inlet and a second inlet, the first inlet is connected to the outlet of the sulfonation reactor; the inlet of...

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a gas-liquid separation device based on chemical production to solve the problem of storing water in the water tank after the gas-liquid separation of the existing gas-liquid separator, and it is very troublesome to manually control the discharge when discharging the water. , it cannot be discharged automatically after reaching a certain liquid level, and if the water inside the water tank is drained, it is easy to cause the unseparated gas in the gas-liquid separator to leak through the drain port, pollute the environment and the separation effect, and the problem of low practicability
